    Castrol is "handled" by BP these days. Wakefield Castrol as we knew it is no more. 2T is an old spec for Lawn Mowers etc I would go for something better in an Aircraft motor. A Rotax 618 is over 100 Hp/ Litre. My son Races with MOTOR EX as OK for Husqvarna/KTM. Nev

    They had a pretty good BIG magnetic compass's too and you had to KNOW your turning and acceleration Errors. Flying on LIMITED PANEL had to be mastered. I used to PRACTICE IT on the F27, too. Quite Tiring. Nev

    Lot of traffic near some places using different frequencies North of Brisbane and issues with RPT into Ballina getting low. Nev

    SOME crudes are better than Others for Lube Oil. One good example is Pennsylvanian crude Synthetic has many bases eg ESTER based. SOME synthetics way back didn't give much Protection from Oxidisation in 2 strokes and were avoided. Today SOME/Most syn and Mineral oils will mix so you can get Part synthetic and the syn is made from LPG. Most crude has a Lot of sulphur which is highly corrosive when oxidised and the Mixed with water. It has ALMOST been eliminated from the Best Oi/fuel countries, LPG also has impurities but is removed during the manufacturing process. Thickening oils is generally done by adding Polymers which are Plastic like Particles which have a finite Life in lube oils. It would be good if ALL engines were Pre-Pressurised with oil to reduce the damage of dry starts. Nev

    A spinning Plane doesn't pull much G until the recovery dive Pull out. Most Aerobatic Planes have G meters that record a MAX figure. Nev

    What does RED Lettering Mean? Nev

    IF you want to go over big Hills you do need a boosted engine.. Nev

    A lot of money. Nev

    What is the Current Price of that engine? Nev

    All will be revealed. There should be plenty of Data and evidence. Nev

    The ball is the Opposite of a Spirit Level. The coloured fluid damps it movement . It indicates skid or slip. To indicate turn rate you need a Gyro.. Level it relative to the Planes wings to set it up on the ground . Some gyros can be electronic. Nev

    A were a Lot of them at Williamtown RAAF Base before the Sabres and a few RNAC Pilots had a fly of them. No particular Vices and no Swing on take off. Not a lot of Endurance. Goblin Motor. Centrifugal compressor Low thrust and doesn't stall. Nev

    Ther's the end ones too.. Nev

    There was quite a few Vampires sitting around at one time in varied states of decay. They use a bit of runway to get airborne. Nev

    Check the Crank Oils seals also if the Motor has been sitting or a long time since manufactured. Correct Mixture is critical. Nev

    Do you have the Original muffler and oil bottle for the Disc valve drive ? Use the same oil there as in the premix . GL6 in the redrive is no longer available. Might need an additive. Nearly 74 HP output. Nev

    Can you confirm what Model Your Rotax is? Nev

    Rotax are getting out of 2 strokes for Planes. I lot of the reliability is in the hands of the Operator. When they were more universal, I've seen some engines I wouldn't run as a Lawnmower,, still being flown. Little compression and rattly when pulled over. Now they are pretty RARE and there's not a lot of Real Knowledge about them. Even your off road trail BIKES NEED REGULAR SERVICING to ensure a trouble free ride. I've never had a 2 stroke even falter but I'm Very careful WHOSE planes I will fly. I will fly something a bit suss ( do a test) if there's Paddocks all around and no trees to have to climb over. Nev

    Oils in specific countries have varying formula's. Autobarn have a lot of brands but if you say it's for an aeroplane they might clam up. Note the date of the Rotax advice April 2009.. Some of those recommendations may have been superseded . You can call Penrite on the Phone. I've found them very helpful with Lube enquiries. They used to make a product called "Green Slime" But got sued. It required careful mixing. Aero engines operate different to most other applications. They don't get much of a rest. and they are full bore at the beginning. Your biggest worry is carbon build up in the ring grooves and the cold motor fuel washing the oil from the Internals as the fuel is not vapourised. Note also 100 L L is OK and with premix fuel remaining in the carbs will evaporate and leave neat oil which can cause lean running next time. Nev

    Perhaps their formula has changed. ( More mixant?) Makes it seem thinner in the bottle. Nev

    Don't use any TCW3 type oil . Its ONLY for Outboards. ONE USA company certified it's oil for Aviation. Pennsoil I think. It's a few years back. I used Valvoline Racing 2 stroke like many others, did. Nev

    The DRIFTER'S NEVER EXCEED SPEED is not much above it's cruise speed and it's empty weight is slightly below 1/2 of it's Max weight. That's with a 582 and a SB wing. ( the only type I have flown). Good thing. Nev

    Be nice to know what the freezing level was at the time. Nev
  24. facthunter
    It doesn't NEED 100 HP and 2 strokes have the best Power/weight ratio. What is the actual safety issue that is supposed to be being addressed here?. Nev
